Selling a truck with a 6.6 Duramax diesel engine. It's in good shape—air conditioning and everything else works fine. There are some small scratches and imperfections on the paint, and a bit of surface rust behind the wheel well. Both owners took good care of it. The previous owner stored it for 5 years, and I only use it from April to October. Not accepting lowball offers; it's a great truck. I'm selling it because I'm downsizing to a smaller truck and a commuter car.
